So your check engine light is on. Came up as Bank 1 Sensor 2 Post CAT O2 sensor. Great how much is that gonna cost?

Again back to warranties 1 year warranty with an aftermarket part, or 2 years unlimited mileage warranty OEM Factory Replacement parts. Saving a dollar on an inferior part is not always the best route.
Never knew Bosch, Delphi and Denso made inferior parts always thought Bosch was an OEM supplier or at least made thier parts with OEM supplied parts?? " Warranty" looks good on paper but I personally dont feel like paying an extra $75 for a "quality" part that you shouldnt have a problem with in 1 or 2 years anyway.
